Speaker Biography

Dr Jonathan Halls is responsible for Strategic Technology Planning at Cambridge Display Technology Ltd, the UK-based company that pioneered, and continues to lead the development of, polymer light emitting diode (PLED) displays. In this role, Jonathan is responsible for identifying new applications for PLED technology and defining roadmaps for future development. Working alongside CDT's Chief Technology Officer, Dr Jeremy Burroughes, Jonathan is also involved with customer liaison and managing and planning longer term research activities.
Jonathan studied for a PhD at the Cavendish Laboratory, Cambridge, with Professor Sir Richard Friend, one of the inventors of PLED technology, during which he pioneered a novel architecture for polymer solar cells based on interpenetrating polymer blends. Jonathan subsequently worked as a Research Associate at the Cavendish Laboratory engaged in research into polymer LEDs, solar cells and light detectors. Jonathan joined CDT in 2001 to establish an in-house programme on polymer solar cell development, which he led until his appointment as Strategic Technology Planner in 2004.

Company Profile

Cambridge Display Technology (CDT), headquartered in Cambridge UK, is a publicly owned company (listed on the Nasdaq National Market under the symbol OLED), which was spun out of Cambridge University in 1992. Today it leads the research and commercialisation of polymer light emitting device (P-OLED) technology, designed for use in flat panel displays, lighting and photovoltaic applications.
CDT holds an extensive patent and know-how portfolio relating to the use of conjugated polymers and the manufacture of devices based on them.
CDT's technologies are based on organic chemicals that emit light when stimulated electrically, and the resulting devices are used in electronic displays for information management, communications and entertainment, potentially including the next generation of large panel televisions.
Features that drive consumer adoption of the technology include extreme thinness and lightness, lower power consumption, very wide viewing angles, high contrast and very fast video response.
CDT continues to develop the technology with its team of around 100 scientists, and has made dramatic breakthroughs in improved lifetimes and colour values. It also develops P-OLED manufacturing processes at its Technical Development Centre near Cambridge, and supplies ink jet equipment and materials for printing of P-OLEDs.
CDT's business model is broad, including licensing, technology development and technology transfer, skills development and the supply of manufacturing and test equipment. Licenses have been granted to Delta Opto Electronics (Taiwan), DuPont (USA), Dai Nippon Printing (Japan), Eastgate (Singapore), MicroEmissive Displays (UK), Osram (Germany), Seiko Epson (Japan), Sumitomo Chemical (Japan) and others.
CDT has a joint venture operation with Sumitomo Chemical called Sumation, which is the focus for the development and supply of materials used in P-OLED displays.
Many of the world's display makers have active P-OLED research and development programmes and CDT works with a number of them to jointly develop the technology.
